Hello All
I have an old PC here that is in its twilight years... an HP corporate SFF with a C2D e6550
Win 10 runs ok but I was curious if a Q9300 would help breath a bit more life into it. They're fairly cheap on eBay.
Thoughts?
More Ram and a SSD would likely speed it up more than a Q9300 would, also does the motherboard in that SFF support the Q9300, its possible itll need a BIOS update to get that support.
Yep, I already cloned the spinning rust to a (cheap) sata SSD with Macrium

Hmmm.. but the q9300 has 6 mb cache, 3mb shared between each half.. the older Conroe cpu has 4 MB? i would think that eve nthen, having double the cores would be much more helpful

At a guess with the C2D that's in this board it may not support the 45nm C2D CPUs or if it does it'll likely not support the later 45nm models or later 45nm Quads. It would help if we knew what motherboard is in the OPs SFF PC, in my experience the late 45nm CPUs didn't get a lot of support on the older 775 chipsets. (If they did it was generally on the expensive high end motherboards with overkill VRMs)
The machine's a HP SFF DC5800, with stock board.... Socket support is OK, and the FSB is the same for these two CPU, I'd hope that at the worst it just needs a BIOS update.
Power delivery and cooling may be an issue thanks for the heads up. I dont know about fitting any aftermarket coolers in there, but perhaps I can finagle another case fan. The q300 is a smaller process, but double the cores as the other cpu, the TDP is 30 W higher 🙁

Thermal wise, in full load it's between a c2d E8xxx and a c2q q9xxx (tested against a e8400 and a q9505). Also from my experience c2d e6550 runs 'hotter' then a c2d e8400 (at least the ones that i had to compare) so the stock cooling should still work.
interesting ill check this out
Thanks
